Hi:
Well here's what I did for the developer:
-----
I have added the following to /usr/bin/.java_wrapper:
LD_LIBRARY_PATH="$JAVA_HOME/lib/$proc/$THREADS_TYPE:/data/httpd/jserv/cicmen
u:$LD_LIBRARY_PATH"
and this to /usr/local/apache/jserv/conf/zone_main.properties:
wrapper.classpath=/data/httpd/jserv/cicmenu
-----
Here's the developer's results:
-----
No change. If I comment out the call to the JNI method it works.
Otherwise I get an internal server error. The loadLibrary() command is
above
this and appears to work correctly. I originally had problems just getting
the loadLibrary() command to work, but that doesn't appear to be the
problem
anymore. It has to do with when I actually try to invoke the method that is
in the shared library. It appears to work fine in a stand alone Java
application, but when I convert it to a Servlet, the problem arises. I
wonder if the package protocol is causing a scoping problem. The java
utility that creates the header file for the shared library has the package
name imbedded in it.

Here's the error messages from the JServ log:

Any ideas why the JNI is not working with JServ. It could be a Java
programming problem, but I'm only the system administrator, not a Java
programmer.
